...sometimes. On current Android systems, "int" and "long" are both 32-bit, so you're okay with jint==int, but if you assume jlong==long you will be disappointed. For portability you may not want to assume jint==int. The JNI types are defined to have specific bit widths, while most C types aren't, so take care with your assumptions. Make sure you always use the JNI types in function prototypes, so at least the arguments are passed in and returned correctly. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
